Stepping into the shoes of young Tasmanians who have been disconnected from the community, the annual Whitelion Bail Out will this year see 150 people incarcerated on Friday.

Choosing between a suspended sentence, solitary, gang and king pin gang, each inmate will require a different minimum bail to be released.

With all funds raised going back into helping Tasmanian youth, the organisation hopes to at least match the $150,000 that was raised last year.

The "inmates" will not receive any special treatment as professional actors take on the role of no-nonsense police officers.

Whitelion assistant state manager Barb Walters said the new inmates had a harrowing night ahead of them.

"The money raised actually allows us to create opportunities [for young people], whether or not it's introducing them to a volunteer mentor or to help them get a job and stay in that job," Ms Walters said.

"Once the inmates actually get to Hobart and when the actors are there acting as police, they will be shocked really quickly.

"The money raised here stays in Tassie to support our mentoring programs."

Launceston MLC Rosemary Armitage, who will be participating in the Bail Out, said it was important to offer help to the younger members of the community.

"At the end of the day, the young people are our future and if you can stop them from going into crime and they can take a different path, it's very important," Ms Armitage said.
